There is usually a "Scoop" for lack of better word over that hole that will allow Air passage

but that is Aimed in such a way to try to deflect any direct access by Road Debris ~

This hole looks like there may have been a cover or flange fitted to it at one point as there are 3 - 4 rivet holes which look like they held something in-place over (or in) the hole.   The other side of this hole is in the fender well.

>> What is the intended purpose of this hole?  The overflow/blowoff tube from the battery was hanging out of this hole, but I would like to re-route it out the the first hole (in the upper left corner) and block this hole off as it allows water and road debris into the battery compartment.
